Two cases of early recurrence after transabdominal preperitoneal inguinal hernia repair

We performed transabdominal preperitoneal inguinal hernia repair in 46 patients (58 diseases), two of whom experienced early recurrence after mesh repair. Case 1 was a 76-year-old man with a bilateral inguinal hernia (recurrence site, left indirect hernia) after appendectomy. The recurrence occurred 1 month after transabdominal preperitoneal inguinal hernia repair. The mesh was dislocated to the lateral side, and we repaired it using the direct Kugel® patch with an anterior technique. Case 2 was a 79-year-old man with a bilateral inguinal hernia (recurrence site, right direct hernia with an orifice >3 cm) after appendectomy. The recurrence occurred 3 months after transabdominal preperitoneal inguinal hernia repair. The mesh was dislocated to the lateral side, and we repaired it using an ULTRAPRO® Plug with an anterior technique under laparoscopic observation. We believe the recurrences resulted from insufficient internal exfoliation and fixation affected by complicated exfoliation of the preperitoneal space with omental adhesion after intraperitoneal surgery.
